Specification of Letters Patent. PatentedNov. 16, 3820.

Application filed September 29, 1919. Serial No. 327,047. b

To (525 whom it may concern Be it known that I, CHAnLns M. Mao- UAMEY, a citizen of the United States, residing a 'lluntington Park, in the county of Los Angeles and State of California, have tions where a uniform heat is required;

The object of my invention is to provide a gas burner construction which will be simple, durable and etlicient, and which may be quickly adjusted to a furnace of any design or pattern.

Another object of my invention is to provide a gas burner construction whereby the fiow of gas through said burner may be readilv controlled and regulated to a nicety, and to provide means whereby air may be mixed with the gas in the exact required proportions, in order to provide a perfect com bustion, thereby eliminating all ofiensive odors, as well as consuming the effective gas units;

Other objects will be disclosed in the following description, will be pointedout in the claims, and embodied in the accompanying drawings, in which:

Figure l is a vertical longitudinal section,

throu h my burner construction, showing it applied to the front wall of a furnace as 1t would appear when in use.

Fig. 2 is a transverse section of my invention taken on the line 2-2 of Fig. 1, viewed in the direction indicated by the arrows.

In carrying out my invention I employ an annular head 10 adapted to be secured to the front wall of the fire box door 11 of a furnace 12, by means of cap screws 18. The door 11 is provided with an annular aperture 14, adapted to be covered by head 10, which is provided with an aperture 15, into which is threaded the pipe 16, which projects through aperture 14, and extends a suitable distance into the fire box of the furnace, and serves as a mixing chamber for the gas and air.

An annular ring 17, the bore of which is of approximately the same diameter as aperture 15 and adapted to register therewith, is secured to the head 10 by means of the cap screws 13, and interposed between the oppodamper plates 23 and 2st sitely disposed surfaces 1( are the spacing plates 18 and19 which are also secured in place by means of the cap screws 13. A rectangular slot is formed .between the edges 20 and 21 of plates 18 and 19, and the oppositely disposed surfaces of head 10 and ring 17, in which are slidingly mounted damper plates 23 and as, provided respectively with the handles 25 and 26. he p 7 are for the purpose or regulating the quantity of air passing into the mixing cha m er 16, and are adapted to meet. at the diametrical center of the bore of ring 17, to cut-oil the flow of air to said mixing chamber, or to be moved outwardly and away from each other so as to admit the desired quantity of air to'said mixing chamber. The oppositely disposed vertical edges of the damper plates are each provided with a, semi-circular notch 27 and 28, so

.as to permit of a complete closure of tie entrance to the mixing chamber 16 when desired, the diameter of the two notches be-: ing approximately the same as the diameter of the reducedend of the burner nozzle.

Projecting outwardly from the ring 17, and preferably formed inte ral therewith are arms 32 and 33, which support on their outer ends an annular plate 35, which is provided with a centrally disposed threaded bore 36 in which a burner nozzle construction is secured; The burner nozzle preferably consists of a stationary and a movable member, the stationary member 38 consists of a gas discharge pipe of cylindrical form provided with a threaded end 37, which engages the threaded bore 36 in the plate 35, the outer end 39 of said pipe being closed, and its exterior annular edge is beveled as at 10. The outer end of the gas discharge pipe is provided with a plurality of radially disgas outlet openings 41, and is exteposed v riorly threaded as at 42 for the reception of the interiorly threaded end of the movable member 44; of the burner nozzle, which memeter of the stationary member, thus forming between the two members an annular gas passage or chamber 46; The outer end of passageway 46 is annularly beveled so as to form a seat 47 against which the beveled end,

of tube 38 contacts, so that when the outer burner nozzle member is reciprocated on the of head 10 and ring trally disposed threaded bore 51 adapted to receive the gas supply pipe SSE-which communicates with pipe 88, and in order to pre vent leakage between these two members, a

gasket 53 is interposed between'plates 35 and 50.

V The operation of my apparatus is as follows: Gas is admitted into the pipe 52 from a suitable source of supply (not shown) and passes into pipe 38,- thence through slots 41' into the annularpassage 46. The movable member 44 is then turned in the proper direction to adjust the angular passage formed between the-seat 47- and the beveled endLO of tube 38, to admit the desired amount of gas into the nozzle" 48 and thence' into the mixing chamber 16. The'handles and 26 are then grasped by the attendant and the dampers 27 and28 are manipulated to admit the necessary amount of air into the mixing chamber 16.

By the above recited construction it will be seen that the proper and desired quantitiesoi gas and air maybe admitted into the mixing chamber to form a perfect combustion, and that the fiowof gas into the-mixing chamber may be completely shut off at a point close to the outlet nozzle, thereby reducing to a minimum the quantity of unconsumed gas which would be admitted into the mixing chamber, thus avoiding any odor.

WVhat I claim is:

1. A gas burner, comprising a pipe adapted to communicate with a source of gas supply, and having a closed tapered end and provided with a plurality of radial perforations adjacent said end, and a sleeve mounted on said pipe adapted for rotatable and longitudinal movement on said pipe, provided with a'tapered seat adapted to engage with said taperedend, and to open and close communication between said pipe and a burner nozzle.

2. A gas burner, comprising a head adaptedto be secured to the front wall of a fur nace, an inwardly projecting open ended pipe supported on said head, a pair of damper plates mounted in guideways in said head, and adapted to project across said pipe, a gas supply pipe supported on arms eXtending outwardly from said plate, and adapted to proj ect into said first mentioned pipe, and

a valve arranged in said gas supply pipe arranged adjacent its inwardly projecting end.

3. In combination with a furnace, or" an open-ended tube arranged in the front wall ofsaid furnace and projecting thereinto, a gas'supply pipe leading to said furnace, the end of said supply pipe terminating'adjev cent the outer end ofsai'd tube, a burner'nozday of September, 1919.
